Small-x, Diffraction and Vector Mesons [PDF]

open access: yes, 2015
This talk discusses recent progress in some topics relevant for deep inelastic scattering at small x. We discuss first differences and similarities between conventional collinear factorization and the dipole picture of deep inelastic scattering.

Ultraperipheral collisions and low-x physics

open access: yes, 2022
Ultraperipheral collisions at the LHC and RHIC offer the highest currently available energy for photon-nucleon and photon-nucleus collisions. Thus they are a valuable tool for studying the gluonic structure of hadrons and nuclei at small x.

Semi-inclusive Deep Inelastic Scattering at Small-x [PDF]

open access: yes, 2009
We study the semi-inclusive hadron production in deep inelastic scattering at small-x. A transverse momentum dependent factorization is found consistent with the results calculated in the color-dipole framework in the appropriate kinematic region.

Azimuthal correlations in diffractive scattering at the Electron-Ion Collider [PDF]

open access: yes, 2022
We calculate azimuthal correlations between the exclusively produced vector meson and the scattered electron in Deep Inelastic Scattering processes at the future Electron-Ion Collider (EIC).

A multi-channel U-Matrix model of hadron interaction at high energy

open access: yesJournal of High Energy Physics, 2023
The present phenomenological study investigates a multi-channel model of high-energy hadron interactions by considering a full parton configurations space and the U-matrix unitarisation scheme of the elastic amplitude, comparing it to the two-channel ...

Exclusive J/ψ and ψ(2S) production inppcollisions at √s=7 TeV [PDF]

open access: yes, 2013
Exclusive J/ψ and ψ (2S) vector meson production has been observed in the dimuon channel using the LHCb detector. The cross-section times branching fractions to two muons with pseudorapidities between 2.0 and 4.5 are measured to be σpp→J/ψ (→μ +μ −)

Vector meson production at low x from gauge/gravity duality

open access: yes, 2013
We use gauge/gravity duality to study vector meson (J/?, ? 0 , ?, ?) production in electron-proton scattering, in the limit of high center of mass energy at fixed momentum transfer, corresponding to the limit of low Bjorken x, where the process is ...

Helicity evolution at small x: quark to gluon and gluon to quark transition operators

open access: yesJournal of High Energy Physics
We include the quark to gluon and gluon to quark shock-wave transition operators into the small Bjorken-x evolution equations for helicity in the flavor-singlet channel derived earlier in [1–3].

Transverse momentum dependent shape function for J/ψ production in SIDIS

open access: yesJournal of High Energy Physics, 2023
It has been shown previously that the transverse momentum dependent (TMD) factorization of heavy quarkonium production requires a TMD shape function. Its perturbative tail can be extracted by matching the cross sections valid at low and high transverse ...
